Grandfathered Plan

Apparently, our current plan is grandfathered.  The price is nothing to brag about.  Anyway, we still haven't upgraded to X1.  We're told that with X1, we can't have the same grandfathered plan at the same price.  We were offered a one-year promotion that would give us the same TV channels (we think:  hard to figure those packages) and Internet speed, and at a savings of about $60 a month.  Nice, but it only lasts a year, and then the price pops up to more than we're paying now.  And, we've lost the grandfathered status, for what that was worth.
